ODBC_NEXT_RESULT(3)							 1						       ODBC_NEXT_RESULT(3)

odbc_next_result - Checks if multiple results are available

SYNOPSIS

       bool odbc_next_result (resource	$result_id)

DESCRIPTION

	Checks	if  there  are	more  result  sets  available  as  well  as  allowing  access  to  the	next  result  set via odbc_fetch_array(3),
       odbc_fetch_row(3), odbc_result(3), etc.

PARAMETERS

	      o $result_id
		- The result identifier.

RETURN VALUES

	Returns TRUE if there are more result sets, FALSE otherwise.

EXAMPLES

       Example #1

	      odbc_next_result(3)

	      <?php
	      $r_Connection = odbc_connect($dsn, $username, $password);

	      $s_SQL = <<<END_SQL
	      SELECT 'A'
	      SELECT 'B'
	      SELECT 'C'
	      END_SQL;

	      $r_Results = odbc_exec($r_Connection, $s_SQL);

	      $a_Row1 = odbc_fetch_array($r_Results);
	      $a_Row2 = odbc_fetch_array($r_Results);
	      echo "Dump first result set";
	      var_dump($a_Row1, $a_Row2);

	      echo "Get second results set ";
	      var_dump(odbc_next_result($r_Results));

	      $a_Row1 = odbc_fetch_array($r_Results);
	      $a_Row2 = odbc_fetch_array($r_Results);
	      echo "Dump second result set ";
	      var_dump($a_Row1, $a_Row2);

	      echo "Get third results set ";
	      var_dump(odbc_next_result($r_Results));

	      $a_Row1 = odbc_fetch_array($r_Results);
	      $a_Row2 = odbc_fetch_array($r_Results);
	      echo "Dump third result set ";
	      var_dump($a_Row1, $a_Row2);

	      echo "Try for a fourth result set ";
	      var_dump(odbc_next_result($r_Results));
	      ?>

	      The above example will output:

	      Dump first result set array(1) {
		["A"]=>
		string(1) "A"
	      }
	      bool(false)
	      Get second results set bool(true)
	      Dump second result set array(1) {
		["B"]=>
		string(1) "B"
	      }
	      bool(false)
	      Get third results set bool(true)
	      Dump third result set array(1) {
		["C"]=>
		string(1) "C"
	      }
	      bool(false)
	      Try for a fourth result set bool(false)

IS_CALLABLE(3)								 1							    IS_CALLABLE(3)

is_callable - Verify that the contents of a variable can be called as a function

SYNOPSIS

       bool is_callable (callable  $name, [bool  $syntax_only = false], [string  &$callable_name])

DESCRIPTION

	Verify	that  the  contents  of a variable can be called as a function. This can check that a simple variable contains the name of a valid
       function, or that an array contains a properly encoded object and function name.

PARAMETERS

	      o $name
		- The callback function to check

	      o $syntax_only
		- If set to TRUE the function only verifies that $name might be a function or method. It will only reject  simple  variables  that
		are  not  strings,  or an array that does not have a valid structure to be used as a callback. The valid ones are supposed to have
		only 2 entries, the first of which is an object or a string, and the second a string.

	      o $callable_name
		- Receives the "callable name". In the example below it is "someClass::someMethod". Note, however, that  despite  the  implication
		that someClass::SomeMethod() is a callable static method, this is not the case.

RETURN VALUES

	Returns TRUE if $name is callable, FALSE otherwise.

EXAMPLES

       Example #1

	      is_callable(3) example

	      <?php
	      //  How to check a variable to see if it can be called
	      //  as a function.

	      //
	      //  Simple variable containing a function
	      //

	      function someFunction()
	      {
	      }

	      $functionVariable = 'someFunction';

	      var_dump(is_callable($functionVariable, false, $callable_name));	// bool(true)

	      echo $callable_name, "
";  // someFunction

	      //
	      //  Array containing a method
	      //

	      class someClass {

		function someMethod()
		{
		}

	      }

	      $anObject = new someClass();

	      $methodVariable = array($anObject, 'someMethod');

	      var_dump(is_callable($methodVariable, true, $callable_name));  //  bool(true)

	      echo $callable_name, "
";  //  someClass::someMethod

	      ?>
